What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study compares standard monofocal intraocular lenses (IOLs) with enhanced monofocal IOLs in 461 people having cataract surgery. The goal is to see if the enhanced lenses improve vision at intermediate distances, like reading a computer screen, while maintaining good distance vision. Participants will receive a different lens in each eye and be followed for several months.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
intraocular lenses (standard monofocal vs. enhanced monofocal)
What this could lead to
If successful, this could show that enhanced monofocal lenses provide better vision at intermediate distances (like computer screens) after cataract surgery, reducing the need for glasses.
What could go wrong
This is a mid-sized trial comparing already-approved lenses, so the differences may be small. Individual results vary, and not everyone may notice a benefit.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 461 people

The number the study aims to enrol. It can still change while the study runs.

Started

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

50 to 100 years

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Bilateral age-related cataract planned for phacoemulsification extraction and posterior IOL implantation * Age 50 to 100 * Visual potential in both eyes of 20/25 or better as determined by investigators estimation * Normal findings in medical history and physical examination unless the investigator considers an abnormality to be clinically irrelevant * Irregular Astigmatism (Acrysof IQ Vivity IOL, IC-8 Apthera IOL) * postoperativ binocular best corrected distance visual acuity (BCVA) ≥ 1.0 decimal (Arm ten (X)) * Standard cataract surgery with bilateral implantation of a monofocal IOL (Vivinex XC1 or Vivinex XY1) (Arm ten (X)) Exclusion Criteria: * Preceding intraocular surgery or ocular trauma * Relevant other ophthalmic diseases that particularly effects the zonular apparatus (such as severe pseudoexfoliation syndrome, preceding cryocoagulation, trauma) * Pupil diameter \< 2.0 mm (photopic) * Laser treatment * Uncontrolled systemic or ocular disease * Pregnancy/Nursing * childbearing ability
